Macroscopic porous media - Dardis and McCloskey model

Hallo everyone,

I am trying to model a flow in a macroscopic porous medium. A reference is Dardis and McCloskey, Phys, Rev. E 57, 4834-7, 1998.
In this model, the miscroscopic structure of the porous medium is not resolved. Rather, a scalar field spanning from 0 to 1 is defined as n(x) = 1 - phi(x), where phi(x) is the porosity.

Has this model already been implemented in Palabos?
Thank you
